To calculate the cost of polishing of circular table, we have to calculate its area first of all.Here, Given diameter of the circular table-top = 2.1m. Hence, r = 1.05 m
Area = π r^2
= 3.14 × 1.05^2 = 3.46185 sq m
Cost of polishing = Rate × Area
= Rs 10 × 2.0096 = Rs 34.6185

Answer:
Step-by-step explanation:
Radius=1.1m
Area of circular table =pi * r^2
22/7*1.1*1.1
=3.80
Cost=3.80×20
76.05 is the cost
